3: Bees are well known for their painful stings that they deliver whenever they percieve a threat. You have adopted this trait of the bee, and now have a stinger that deals damage according to the table below. If you already have a stinger attack, increase the damage of you current stinger by one size category instead.

7: Bee's have evolved to rely heavily on their flight, and are not very capable of getting around without their wings. In turn, you have grown the ability to actually fly, and have gained two pairs of long, transparent wings that allow you to fly at your base speed, with average manueverability. If you already had a flight speed, then you may either have that flight speed increase by 30 feet, or have it improve by one maneuverability category, at your choice.

11: There are certain kinds of bees that inject a kind of pheromone when they sting, that smells particularly strong to other bees, and designates the stung creature as an enemy. You have developed this same kind of adaptation, and can now strike a creature, and drive your buzzing allies to tear it apart. If you strike a creature with your stinger attack, then attack them with your Swarm attack in the same round, then your Swarm attack deals double damage against that individual creature (So, a level 12 hivemaster's swarm would deal 24d6 damage against a creature that had been damaged by your stinger).

15: While an individual bee sting is nothing more than painful, when a swarm of millions of them engulfs something and begins to pepper it with an uncountable number of stings, it's almost impossible for the creature to even think through the inferno of pain that has swallowed it. If you use your Swarm attack on a creature that is below half it's maximum health, then that creature must make a will save or become paralyzed by pain during their round. This is a pain effect.

Special: A character can only have a number of [Symbiotic] feats equal to the number of times that they have gained the Aspect of the Vermin class feature.
